wassname 409d9c9425 refactor: SVD-diag knob -> parametrized LoRA (fixed A, train B)
Replace the AntiPaSTO SVD-diag adapter (δW = U·diag(δS)·Vh) with a parametrized
LoRA: per Linear a frozen random A (r×d_in, semi-orthonormal) and a trained
B (d_out×r), δW = (B+B_hack)·A. δW stays LINEAR in the trained knob -- the one
property the projection needs (a once-extracted V stays a fixed weight-space
direction) -- but the whole per-module SVD subsystem is gone (no svd_cached, no
SVD_CACHE, no bf16 hash/contiguity friction). B_hack is the SAME shape as B, so the
route quarantine is capacity-matched by construction (old-repo route2 diverged from
an oversized quarantine sink).

- antipasto: wrap() builds A (fp32 orthogonal_, geqrf has no bf16 -> cast after) +
  B/B_hack zero-init on the layer device; forward y + (B+B_hack)@(A@x).
- proj: project_one is dim-agnostic; project_all flattens B.grad (d_out·r) and
  reshapes back. cos_overlap flattens too.
- extract: V from the SVD of stacked B.grad pair-diffs (d_out·r).
- train: B/B_hack rename, lora_rank config, per-step aligned table + legend
  (replaces the sparse tqdm postfix), clean argv via preset/Config defaults.
- justfile: collapse smoke-vanilla/smoke-route/fast-vanilla/full-vanilla into
  smoke/fast/full *ARGS + a `sweep` recipe that fires vanilla|erase|route as pueue
  jobs. results.py: glob run_*.log (skip loguru verbose logs).

Smoke (GPU bf16, all three arms) green: cout~0 one_sided identity holds in the LoRA
basis, |Bh|=0 for erase/none, route parks into B_hack.

"""Audit a training run's per-step jsonl: quote first/last student generation
(coherence eyeball) + summarise the key columns with first-vs-last5 trend arrows.
Deterministic extraction; the /audit-log command feeds this to the LLM for a verdict.
The clean repo writes ONE jsonl per run (logs/run_<arm><tag>_s<seed>.log) -- each line
is a metric row, and rows that had a live student rollout carry a `gen` field
{text, hack, gt, reward}. No separate rollouts.jsonl.
Usage:
uv run python scripts/audit_log.py logs/run_erase_s41.log # a specific run log
uv run python scripts/audit_log.py # newest logs/run_*.log
